目的 评价限时饮食对超重/肥胖人群的干预效果，以期为相关人群饮食护理提供依据。 方法 检索 PubMed、Cochrane Library、Embase、Web of Science、CINAHL、中国生物医学文献数据库、中华医学期刊全文数据库、知网、万方、维普等数据库中有关限时饮食应用于超重/肥胖人群的随机对照试验，采用Revman 5.3软件进行分析。 结果 共纳入8篇文献，共440例参与者，其中干预组218例、对照组222例。与常规饮食相比，限时饮食能明显改善超重/肥胖人群的体重、血压和空腹血糖（均P＜0.001）；但在改善血脂方面，差异无统计学意义(P＞0.05)。 结论 限时饮食可明显改善超重/肥胖人群的体重、血压和空腹血糖，在改善血脂方面效果不明显，需更多高质量研究论证。

Objective To evaluate the intervention effects of time restricted feeding in obese or overweight people，and to provide basis for nursing of related population. Methods The randomized controlled trials on the application of time restricted feeding in obese or overweight people in PubMed,Cochrane Library,Embase,Web of Science,CINAHL，CNKI,Wan fang,VIP and Sino Med were searched by computer,and analyzed by Revman 5.3 software. Results A total of 440 participants,218 in the intervention group and 222 in the control group were included in 8 studies.Compared with routine diet,time restricted feeding could significantly improve the weight,blood pressure and fasting blood glucose of obese or overweight people (P＜0.001),but there was no significant difference in improving blood lipids (P＞0.05). Conclusions Compared with routine diet,time restricted feeding can significantly improve the weight,blood pressure and fasting blood glucose of obese or overweight people,but it has no obvious effect on improving blood lipids.More high-quality studies are still needed in the future.
